RULE-PUNCHING M ECHANjfSM.

Application filed May 2, 1923, Serial our invention relates to devicesfor punching' or notching type-bars, slugs and rules to receive insertedcolumn-rules of the so-called lino-tablar form, extending'transverselyof the punched typehars and rules. It is the particular object 015 ourinvention to" provide,

a punchfor producing small triangular or wedge-shaped notches opening tothe printing face of a type-metal rule or rule-slug, in which the punchor perforating member is'so' guided and supported as' not to beliavble'to deflection, bending or breakage, by continued use for thepurpose forwhich it is intended. A further object'of our invention is toprovide a rulenotching punch mechanism wherein the depth of the notchesis gaged solely with re spect to the printing faces of the rules orslugs, so that variations in the height'ot' the punched members willnotaffect the relative height of the inserted column-rules, and theprinting faces of the latter will be always perfectly alined with otherprinting-faces of a form. A further object of our invention is toprovide a simple and convenient mechanism adapted. to securely hold anassemblage or gang of punch-units, together with a plurality. of spacingplates and gages, in positive and definitely alined relation to eachother, whereby any desired number ofnotche's may hem-ado simultaneouslyin a type-metalv rule, type-bar or slug, the notches being accuratelylocated longitudinally ot the rule or slug and also with referencetotheprinting-face thereof, and the punching operation repeated to produceany number of parts notched in exact duplication of each other. Ourinvention further comprises means by which a plurality of punch-unitsmay be assembled and held in a definitelymeasured relation toeachiother, determined by the thickness of spacing members iuterspaced withthe punch-units, the spacing members beingxof standardized thickness andvarying only in multiples of a fixed unit-thickness. More particularobjects of our inventionwill appear hereinafter.

In carrying out our invention according to the illustrated embodimentthereof, we provide a plurality of punchese'achof which is formed from aflat steel, bar 20 of rectangular sectional form, the thickness of thebar being slightly more than the greatestwidth oi the notchesto bef'orme'ch The lower rear portion oithe bar is recessed at each side toleave a thin flat blade 21 of which the front edge merges into thetriangular or wedgeshaped part 22, the latter:eoinprising 'the punchproper or perforating. member, and the widest portion thereof being:alined' with the front-edge of the bar 20.; as-shownin'Fig. The blade211 projects'ifora short distance below thelower endof the triangularpart 22; and the front edge 2310f fsaid projecting portion forms a gagefor limiting-the distance to whicha rule or slug-may be inserted beneaththe-cutting edges at the lower end of the part 22; Near the'upper end ofthe bar -20 a notch'fl l is formed in the rear side there of forreceiving the actuating member. At about the level of the lower side'ofthe notch 24* there is a transversely extending's'top-pin 25whichprojects slightiyat eaehsi'deof the bar. Theguide or housing-forthepuneh is formed by two symmetrical parts- 26 and'27 which aresecured'together by aplurality of screws 28, said screws entering.threaded openingsin the part" 26, and=the flat heads of thescrewsbeingxeountersunk in the part 27.

The adjacent sides of the parts 26 and 27 are channeled to form apassage for receiving the punch-bar slidably between them, the width ofthe channel bein greater at the upper portion than at the lbwer portion,so that both the main upper portion of the bar and the thin web or blade21 at the lower portion are guided and supported laterally as shown inFig. 9. At the front side of the housing, near the lower end thereof, isa rectangular transverse recess 29 which intersects the front portion ofthe channel for the punch-bar, so that the-rear end of said recess 29 isslightly behind the gage-surface 23 at the front edge of the bladeQl, asbest indicated in Fig. 7'. The portion of the housing beneath saidrecess 29 forms the die-block which supports the work and into which thelower end of the part 22 passes at the completion of a punchingoperation. The opening for said part 22 fits the same closely for ashort distance below the recess 29, and a larger clearance-opening 30extends therefrom to the bottom of the housing, as best shown in Fig. 8.The punch-bar may be withdrawn from or inserted into the upper end ofthe housing, and the stop-pin 25 limits the depth to which the bar mayenter the housing. Below the recess 29 the front face 31 of the housingis inclined forwardly, and a corresponding rearwardly inclined face 32is formed atthe back of the housing, said inclined faces 31 and 32 beingaccurately positioned with respect to the punch, so that when said facesare'engaged by the hereinafter described clamping means a series of thepunch-units may be properly alined with each other.

Referring now to the holding and actuating means for the describedpunch-units, in the preferred and illustrated embodiment thereof weprovide an integral base-member 33 having perforate foot-portions 34adapted to be secured by bolts orscrews to a suitable support. The upperside of said base-member is a plane-surfaced table, except at the rearedge where there is an upwardly projecting flange or gib 35, the frontface of which is undercut so as to fit against the rear inclined faces32 of the punch-housings when the lower ends of the latter rest upon thetable. Said flange or gib 35 thus forms a fixed clamp-member whichserves to accurately aline any. number of the punch-units. A; parallel,coacting, movable clamp-member is formed by a bar 36 which is mountedpivotally in a recess or trough 37 extending longitudinally of the baseintermediate its front and rear sides. The clamp-bar 36 extends abovethe table suificiently to engage the inclined faces 31 at the frontsides of the punchhousings, the rear side of the bar being undercut tofit against said faces. In the lower portion of the trough 37 is a rod38 of which the ends are held in the end-portions of the base, and atubular sleeve 39 is disposed upon the rod intermediate saidend-portions. Lugs 40 on the lower portion of the clampbar 36 fitpivotally about said sleeve 39, and

the central one of said lugs 40 is cut away at the rear side so that ascrew ll, which extends through the rear side of the trough, may en gagethe sleeve as shown in Fig. 6. A plurality of small coil springs 42 aredisposed in pockets formed in the rear side of the clampbar, saidsprings engaging the rear side of the trough and tending to swing thebar forwardly away from the punch-housings. Clamp-screws 43 extendthrough the base from the front. side thereof, said screws having wingedheads, as shown, and the rear ends thereof being engageable with theclamp-bar to press the samefirmly against the faces 31 of thepunch-housings. As said clamp-screws engage the'bar 36 at pointsintermediate the punch-housings and the fulcrum-rod 38, there is atendency to bend said rod rearwardly, and the screw 11 is used toprevent such bending of the rod.

Between the gib 35 and clamp-bar 36 the table is slotted from end toend, the slut being parallel with the clamping members. In said slot atthe ends of the base are fitted hearing blocks 4%, and a similar block45 is disposed at the middle of the slot, said blocks being fixedly heldin place by means of setscrews 46 extending through the base from therear side, as shown. Said bearing-blocks support revolubly the ends andcentral portion, respectively, of a shaft 4:7, of which one end isextended beyond the base and carries a crank 48. The portions of saidshaft intermediate the center-block 45 and end-blocks 4A are threaded toform right-hand and lefthand leadscrews, on which are mounted thevice-jaws -19. The lower portions of the vice jaws fit slidably in theslot of the table, and the upper portions of said jaws extend above thesurface of the table, as shown in Fig. 11. By rotation of the crank 48the jaws are moved toward or away from each other, according to thedirection of rotation.

A rocking-shaft 50 extends longitudinally through th rear portion of thelame, beneath and parallel with the gib 35, and upon the projectingend-portions of said shaft are fixedly secured the arms 51 and 52 whichcxtend upwardly therefrom. Said arms have rcarwardly projecting lugs 53intermediate their upper and lower ends, and between said lugs thecross-rod 54 is fixedly secured. An arm 55 is formed integrally with thearm 59., and extends forwardly from the rockingshaft,alongside the endof the base and beneath the projecting end of the vice-screwshaft a7. ahead 56 in which a latch-pin .37 is slidably held. A small coil spring,indicated by dotted lines in Fig. 1, is arranged around the latch-pinwithin the head 56, said spring en- At the front end of the arm 55 isgagin a shoulder on the pin and pressing the sameton' -ard the base. Anopening is formed in the end of the base for receiving the inher end ofthe latch-pin, and when the same is entered in said opening it holds infixed normal position the rocking frame comprising the arms 51, 52 and55, the shaft 50. and the cross-rod 54. The punch-actuating lever ismounted. pivotally between the upper ends of the arms 51 and 52, saidlever coi'nprising a bar 58 having an integrai forwardly extending lip59, termii'lating in a rounded head 60 adapted to lit within the notchesQel of the punch-bars, and a handle 61 secured upon the central portionof said bar and extending upwardly therefrom. Screws 62 extend throughthe frame-arms 51 and 52 into the ends of the bar 58 to form the pivotalconn'ection of said members. Near the ends of the bar 58 are rearwardlyprojecting fingers 63, and from said fingers the tension springs 64extend downwardly to connect with eyebolts 65 on the rear side of thebase. At one end of the bar 58 is an upwardly extending lug 66 having athreaded opening therein to receive an adjusting-screw 67, the rear endof said screw being adapted to engage a stop lug 68 on the arm 51,whereby to limit the lifting movement of the actuatingdever, as effectedby the springs 64. By grasping the head of the latch-pin 57 and pullingsaid pin outwardly to disengage the same from the base, the rockingframe is released and may then be tilted backwardly to a position suchas shown by dotted lines in Fig. 2. The punch-actuating lever is therebydisengaged from the punch-bars, and the space above the clan'ipingdevices is cleared to provide easy access to the parts held thereby.

In the table or top of the base, in front of the trough 37, there is arectangular groove which extends at one end through a lug 690n the endof the base. In said groove is slidably disposed a bar 70, the samebeing retained in the groove by a thin cover-plate 71. At the front sideof the lug 69 is a knurledhead set-screw 72 which may be tightenedagainst the bar to hold the same in longitudinally adjusted positions.To the upper side of the bar, adjoining said lug69, there is secured afinger plate 73 which extends rearwardly and has a vertical lug 7 4integral therewith. Said 111g 74 forms an end-gage for positioning longrules or the like with respect to punches held by the vicejaws andclamped between the gib 35 and clamp-bar 36. For short rules, and fortypeslu'gs and the like, the longitudinal position with respect to thepunches is gaged bymeans of plates 75 which are clamped in the holdingdevices in the same manner as the punch housings. One of saidgage-plates 75 is ind icat'ed in Fig. l. adjoining each of the viceiaws.The thickness of thepunch-housings is preferably a unit of printersmeasure,

usu'al-lyone pica, so that it" a series of the housings are assembled inthe holding means alongside each other, the punches will be positionedtor notching rules and the like at points spaced apart one pica. When aseries of the punch-housings are so assembled, if it should be desiredto omit the notches at one or more points on the rule, the punches maybe removed from the respective housings,

and the remaining punches then operated without changing the assembly ofthe housin gs. To avoid the use of. an excessive number of thepunch-housings for filling out the desired longitudinal spacing of thepunches to be operated, we also provide a plurality of spacing-plates76, which are of the same outline form as the lower portions of thepunchhousings, so as to fit between the clamping i'i'iembers and 36,but. of which the thickness is varied so that by suitable combinationsof the plates any desired spacing of the punches may be attained.Preferably, the thickness of the spacing-plates is varied in multiplesof the point unit of printers measure, some of the plates being, forexample, two-points thick, others six-point, and others twelvepoint orone pica. The ordinary spacing-plates 76 are recessed at their frontedges to the same depth as the recesses 29 of the punch-housings, sothat when a rule or rule-slug with athin hair-line printingface isinserted for punching, said printingi'ace will not be marred or deformedby engaging the ends of said recesses, but will engage only thegage-races 23 of the punchblades 21. As the portions of theprintingfaces so engaged with the faces 23 are cut away by the operationof the punch s, it will be apparent that the remaining portions oi? thepi-intiin daces of the punched rules will show no deio nation, even itthe rules should be pushed against the gage-faces 23 with an necessaryforce. 7

Referring to Figs. 13 and 14, there is shown a special form of thespacing-plates,

761, whereinthe recesses are formed with a shoulder or offset 77,beneath which a thin slot 7 Sextends back to at least the depth of therecesses 290i the punch-housings. When punching thin rules A, one ofsaid special plates 76]. is preferably disposed alongside each of thepunch-units, so that, when a rule is inserted for punching, the samewill extend into the slot 78 as shown in Fig. 14. The plates 761, whenso employed, serve as strippers to prevent lifting of the rule duringthe withdrawal of the punches therefrom, which might deform the notchesor the printing-face of the rule. The special plates 761 are alsoemployed when punching a type-bar or slug B with a rule-face, such asindicated in Fig. 13. For this purpose the shoulder 77 is so located asto engage the shoulder of the slug B when the same is inserted to theproper depth beneath the punches. It should be noted that the slug B isof the character formed by linotype and similar type-bar castingmachines, wherein the shoulder of the slug is always at a uniformdistance from the printing-face, although the over-all dimension of theslug may not be exactly typc high. It will thus be seen that when thepunched notches are gaged from the shoulder of the slug the notches willbe located in the same relation to'the printing-face as if gageddirectly from said face, and without liability of the printing facebeing marred by the gage.

In the preparation of ruled printingtorms it is often desirable toemploy typeslugs C of the character indicated in Figs. 15 and 16, havingat one or more places intermediate the type-faces c lugs 79 which may bepunched or notched to receive linotabla r colunmrules of which thebase-portions will rest upon the shoulders of the slugs. For use withtype-slugs of this kind, we provide special gage and spacing-plates 702,one ofwhich is shown in Fig. 12, in connection with one of thepunch-units. Said plate 762 has in the front side thereof a rectangularrecess similar to the recess 29 of the punch-housing, but with the end81 of said recess slightly in front of the end of the recess 29, whichis indicated by a dotted line in said Fig. 12. l/Vhen the plates 762 areassembled with the punch-units in the clamping mechanism, said end-faces81 are alined with the gage-faces 23 of the punches. When the slug C isinserted for punching, the type-' faces a engage the surfaces 81,, andthe lugs 79 are thus positioned with respect to the punches as shown inFig. 7, so that the .notches punched in said lugs are properlypositioned for holding the inserted rules with their printing faces atthe same level as the type-faces.

From the foregoing the general operation of the mechanism will beapparent. \Vhen changes are to be made in the arrangement of thepunch-units, the latch-pin 57 is pulled out to release the rocking framewhich carries the punch-actuating lever, and said frame is tiltedbackward to disengage the lever from the punches. The crank 48 is thenturned to move the vise-jaws 4-9 apart, and the clamp-screws 4.3 areturned to relieve the pressure of the clamp-bar 36 against thepunch-housings and spacing-plates. Said members can then be removed oradditional members inserted in the holding mechanism in the properarrangement according to the workto be done, after whichthe crank 48 isturned to press the vise-jaws lightly against the ends of theassemblage, then the clampscrews 43 turned to press the parts lightlyagainst the gib 35 to properly aline them, and finally both the vise orside-clamping means and the bar 36 or end-clamping means tightened up tosecurely hold the parts in alined and adjusted relation. For shortrules, and for type-bars and sings, the longitudinal relation thereof tothe punches is gaged by means of the plates 75, which are arranged atthe proper distance from the punches. For rules of which the length isgreater than can be accommodated by one of the plates held between thevisc-jaws, the lug 7a is employed as an end'gage, the bar 70 beingadjusted to hold the lug in the desired position, and the bar beingsecured in adjustment by the screw 72. After clamping the punch'units,spacing-plates and gages in the desired positions, the rocking frame isswung forward to engage the head 60 of the punch-actuating lever in thenotches 2a of the punch-bars, said frame being retained in operatingposition by the latchpin 57. The rules or type-bars to be punched arethen inserted beneath the punches, being pushed lightly rearward againstthe gaget'aces,and the lever-handle 61 then pulled forwardly to forcethe punches down through the work. The chips or punchings pass downthrough the clearance-openings 30 into a longitudinal groove in thetable, from which they may be removed from time to time, as necessary.

It will be obvious that by the formation of the perforating members 22integrally with the blades 21, and the guiding and supporting of saidblades at their sides and rearward eugc, the members are effectuallyprevented from being deflected, bent or broken by normal and properusage of the mechanism. It will also be apparent that by the use of thespacing-plates 76 of standardized thickness, and the use of thevise-jaws to press the assemblage firmly together longitudinally of thealining clamp members 35 and 36, the punches may be easily located inexact and measured relation to each other, and retained in such relationduring operation upon any number of parts.
